Yesterday my car would not shift at all. I am not sure if it was in second or not. I check the fluid level it was fine and did not smell or looked burnt. So I let it sit over night. After reaqding a little bit on this forum I wanted to test and see if the speedo worked. It work and so did the transmission. It shifted just fine. So I was wondering will a bad speed sensor do something like this. I did the key dance and did not get any codes for tranmission. Thanks for any help..
